DISPLAY DEVICE.

To all whom it may concern Be it known that I, JOSEPH M. DANN- HEIsER, acitizen of the United States, and a resident of the borough ofManhattan, in the county of New York, city and State of New York, haveinvented certain new and useful Improvements in Display Devices, ofwhich the following is a specification.

rlhe object of the present invention is to provide a changeable displaydevice of a simple and reliable construction.

The invention may be applied to a great variety of uses such as for thedisplay of changeable signs, for annunciators for railroad stations orcars, for price announcements, for feeding lantern slides or otherpictures, for calendars, &c.

The invention consists in a gravity feed system of handling displaydevices, and of such other features as will more fully hereinafterappear.

In the accompanying drawings the invention is disclosed in a concreteand preferred form, constituting one example of the invention.

In the said drawings: Figure 1 is a side elevation of a device embodyingthe invention. Fig. 2 is a view looking in the direc tion of the arrow 2of Fig. 1. Fig. 3 is a detail of the releasing device and displaysupport.

Similar characters of reference indicate corresponding part-s in theseveral views.

1 indicates a magazine provided in the i present instance with sidesupports 2 and an open end 3.

al are the display devices provided here with transversely extendingsupports 5 which rest on the side supports 2. A latch 6 is providedwhich acts on the outermost display device to prevent its exit from theopen end of the magazine. The latch is here shown as a lever normallyheld up by the spring 7. In order to make the magazine reversible, bothends are open and two latches are provided as shown. This magazine issupported here in an inclined position on the bracket S. Adjacent tothis bracket is a guide 9 through which the display devices are adaptedto be bodily dropped. Arranged in connection with the guide is areleasing device 10 which, when actuated, depresses the latch andpermits a display device to move out of the magazine. The guide 9 isprovided with openings or windows 11 for exhibition purposes and has aSpecification of Letters Patent.

display support 12 on which the display devices drop from the magazineand which acts to arrest the said display devices and causes them to beexhibited.

The releasing device 10 and display support 12 are here shown as pivotedmembers connected by the rod 13. Suitable means are provided foroperating the members 10 and 12, here shown, for convenience, as aweighted lever 14 and cord 15. The mem bers 10 and 12 are so timed thatwhen the cord is pulled, the support 12 releases the display devicecarried by it before another display device is released by the magazine.

The member 12 is provided with an auxiliary support 16 which comes intoposition and arrests the display device released from the magazine. Whenthe cord is released the Adisplay device is 4moved from the support 16to the support 12. The display device on the support 12 may drop into alower magazine of the same construction as the upper magazine. Thesemagazines are preferably removable and interchangeable.

What is claimed, is:

1. In a system of exhibiting display devices, a guide, means forsupporting and exhibiting a display device in said guide, a releasingdevice associated with said guide, a removable magazine containingdisplay devices, a latch on said magazine adapted to normally preventthe display devices from moving out thereof, which when the magazine isproperly positioned becomes operatively associated with the releasingdevice,

and means for operating the releasing device whereby the display devicesare caused to move out of the magazine onto the supporting device.

2. In a system of exhibiting display de vices, a guide, means forsupporting and exhibiting a display device in said guide, a releasingdevice associated with said guide, a removable, double ended andreversible magazine containing display devices, oppositely disposedlatches on said magazine adapted to normally prevent the display devicesfrom moving out of either end thereof, a bracket on which the magazinecan be supported with either end adjacent to the releasing device, andwhereby when the magazine is so supported the latch on that end of themagazine which is adjacent to the releasing device becomes operativelyassociated therewith, and means for operating the releasing devicewhereby the display devices are caused to move out of the magazine fonto the supporting device.

3. In a system of eXhibiting display devices, interchangeable upper andlower open ended magazines, display devices in said upper magazine, aguide interposed between the'two magazines, means for supporting andexhibiting a display device in ciated with the releasing means on theguide, and means for operating the releasing device and the supportingmeans, Awhereby the display devices are caused. to

drop bodily from the upper magazine to the supporting device and fromthe latter to the lower magazine.

4. In asystem yof exhibiting display devices, interchangeable upper andlower magazines, display devices in said upper magazine, a guideinterposed between the two magazines, means for supporting andexhibiting a display device in said guide, a releasing device associatedwith said guide, latches on said magazine adapted to normally preventdisplay devices from moving out thereof, whereby when either magazine isproperly positioned with respect to the releasing devices, the latch ofsuch magazine becomes operatively associated with the releasing deviceof the guide, and means for operating the releasing device to cause thedisplay devices to move bodily from the upper magazine to the supportingdevice.
